Description
本发明涉及换电领域,具体涉及一种储能单元的可调节安装组件。The present invention relates to the field of power exchange, and in particular to an adjustable mounting assembly of an energy storage unit.
随着新能源汽车的普及,如何有效地为能量不足的汽车提供快速有效地能量补给成为车主和各大厂商非常关注的问题。以电动汽车为例,当前主流的电能补给方案包括充电方案和电池更换方案。其中电池更换方案是直接用满电电池更换电动汽车的亏电电池。相对于充电方案,电池更换方案由于可以在很短的时间完成更换且对动力电池的使用寿命没有明显的影响,因此是电能补给的主要发展方向之一。电池更换方案一般是在充换电站内完成。具体而言,充换电站内配置有充电架和换电平台以及在充电架和换电平台之间的运载满电/亏电电池的换电小车,即通过换电小车完成对停于换电平台上的电动汽车进行电池更换。换电小车可以通过定位机构对动力电池进行定位,并使动力电池上的安装结构(如螺栓)与焊接于汽车车身上的对接结构(如与螺栓对应的螺母)对应连接的方式,完成为电动汽车安装满电电池的动作。With the popularization of new energy vehicles, how to effectively provide fast and efficient energy replenishment for vehicles with insufficient energy has become a matter of great concern to car owners and major manufacturers. Taking electric vehicles as an example, current mainstream power supply solutions include charging solutions and battery replacement solutions. Among them, the battery replacement scheme is to replace the depleted battery of the electric vehicle directly with the full battery. Compared with the charging scheme, the battery replacement scheme is one of the main development directions of electric energy replenishment because it can be replaced in a short time and has no obvious influence on the service life of the power battery. The battery replacement scheme is generally completed in the charging station. Specifically, the charging and replacing platform is equipped with a charging stand and a power exchange platform, and a power-exchange trolley that carries a full/depletion battery between the charging stand and the power-changing platform, that is, the power-changing car completes the stop-and-go power change. The electric car on the platform is replaced by a battery. The electric vehicle can be positioned by the positioning mechanism, and the installation structure (such as the bolt) on the power battery is connected with the docking structure (such as the nut corresponding to the bolt) welded on the vehicle body, and the electric motor is completed. The action of installing a fully charged battery in a car.
然而上述电池更换方案存在的主要问题在于:由于动力电池尺寸较大,使得与动力电池上的安装结构对应的对接结构横跨汽车车身的多个位置,累计误差较大。又由于对接结构是以焊接的方式固定于汽车的车身,无法减小或消除上述累计误差,再加上换电小车自身的定位精度也存在误差,这就决定了换电小车在进行动力电池的安装时,往往需要几次、甚至多次定位后才能完成动力电池的安装。解决此类问题的方式之一是提升换电小车的定位精度,但换电小车作为充换电站内的换电***中的一部分,其内部结构复杂,且涉及到的相关***较多,所以改进难度大、改进成本相对较高。正是由于上述原因,导致了换电小车不能快速有效地为电动汽车更换动力电池,降低了换电服务的服务质量。
However, the main problem with the above battery replacement scheme is that due to the large size of the power battery, the docking structure corresponding to the mounting structure on the power battery spans multiple positions of the vehicle body, and the cumulative error is large. Moreover, since the docking structure is fixed to the body of the automobile by welding, the above accumulated error cannot be reduced or eliminated, and there is also an error in the positioning accuracy of the changing trolley itself, which determines that the electric vehicle is in the power battery. When installing, it often takes several or even multiple positioning to complete the installation of the power battery. One of the ways to solve such problems is to improve the positioning accuracy of the electric-changing trolley. However, as a part of the power-changing system in the charging and replacing station, the electric-changing trolley has a complicated internal structure and many related systems involved, so it is improved. It is difficult and the cost of improvement is relatively high. It is precisely because of the above reasons that the replacement electric car cannot quickly and effectively replace the power battery for the electric vehicle, thereby reducing the service quality of the electric service.

在此提出的示例性实施方式,通过提供一种动力电池的可调节安装组件,来克服现有技术中换电小车在为新能源汽车更换动力电池时,由于换电过程中存在累计误差而导致的换电效率低等缺陷。具体而言,通过可调节安装组件以无需拆卸的方式固定在电动汽车车身或者充电架上,并且可调节安装组件上具有可以与动力电池的安装螺栓匹配连接的对接孔的方式,完成动力电池在电动汽车的车身或者充电架上的安装固定。The exemplary embodiment presented herein overcomes the prior art shifting trolley when replacing a power battery for a new energy vehicle by providing an adjustable mounting assembly of the power battery, resulting in a cumulative error during the power exchange process. Defects such as low power exchange efficiency. Specifically, the power module is completed by the adjustable mounting assembly being fixed to the electric vehicle body or the charging stand without disassembly, and the adjustable mounting member has a docking hole that can be matched with the mounting bolt of the power battery. The body of the electric car or the charging stand is fixedly mounted.
首先参照图1和图3A,图1是本发明的动力电池的可调节安装组件的结构示意图,图3A是本发明的动力电池的可调节安装组件的一种优选实施方式的安装过程示意图一。如图1所示,本发明提供了一种动力电池的可调节安装组件,该可调节安装组件主要包括第一对接件1与第二对接件2。其中,第一对接件1可以固定连接于待安装部,第二对接件2可以在第一对接件1的设定范围内移动并且与动力电池配合连接。也就是说,第二对接件2可以在第一对接件1的设定范围内移动以调整动力电池与待安装部之间的相对位置,吸收换电过程中的累计误差,从而使动力电池更加快速的连接到待安装部。需要说明的是,待安装部可以是电动汽车的车身4(参见图3A)。设定范围可以是在动力电池安装的允许误差范围内,允许第二对接件2移动的范围。也就是说,可调节
安装组件的第一对接件1可以固定连接于车身4上,在第一对接件1固定好后,第二对接件2可以相对于第一对接件1在设定的范围内移动,并且此移动能够通过吸收累计误差的方式,使动力电池在允许的误差范围内固定于车身4上的安装位置。本领域人员可以理解的是,也可以将该可调节安装组件设置于与电动汽车的车身4等同的待安装部,如在充换电站内的充电架也采用通过悬挂式固定电池的情形下,充电架上固定单个动力电池的仓结构的顶部也可以视作待安装部。1 and 3A, FIG. 1 is a schematic structural view of an adjustable mounting assembly of a power battery of the present invention, and FIG. 3A is a first schematic view of a mounting process of a preferred embodiment of the adjustable mounting assembly of the power battery of the present invention. As shown in FIG. 1, the present invention provides an adjustable mounting assembly for a power battery, the adjustable mounting assembly mainly comprising a first docking member 1 and a second docking member 2. The first docking member 1 can be fixedly connected to the to-be-installed portion, and the second docking member 2 can be moved within the set range of the first docking member 1 and can be mated with the power battery. That is, the second docking member 2 can be moved within the set range of the first docking member 1 to adjust the relative position between the power battery and the portion to be mounted, absorbing the accumulated error during the power exchange process, thereby making the power battery more Quickly connect to the part to be installed. It should be noted that the to-be-installed portion may be the body 4 of the electric vehicle (see FIG. 3A). The setting range may be a range that allows the second docking member 2 to move within the allowable error range of the power battery installation. That is, adjustable
The first docking member 1 of the mounting assembly can be fixedly coupled to the vehicle body 4. After the first docking member 1 is fixed, the second docking member 2 can be moved within a set range with respect to the first docking member 1, and the movement The power battery can be fixed to the mounting position on the vehicle body 4 within an allowable error range by absorbing the cumulative error. It can be understood by those skilled in the art that the adjustable mounting component can also be disposed in a portion to be mounted equivalent to the body 4 of the electric vehicle, such as when the charging stand in the charging station is also fixed by a hanging type. The top of the bin structure to which a single power battery is attached to the charging stand can also be regarded as the portion to be mounted.
进一步参照图1,第二对接件2主要包括第二对接底板21以及设置于第二对接底板21的可供螺栓穿过的的对接结构22,动力电池上设置有与该对接结构22对应匹配的安装结构3(参见图3A),在安装结构3伸入对接结构22的情形下,安装结构3可以通过与对接结构22配合连接的方式使动力电池固定于安装位置。优选地,对接结构22可以为带有螺纹孔的螺母。对应的安装结构3可以为与螺纹孔匹配螺接的螺栓。当然,对接结构22与安装结构3的形式并不唯一,本领域技术人员可以根据具体应用环境对其形式作出调整,只要该形式可以满足对接结构22与安装结构3匹配连接后可以使动力电池固定于安装位置的条件即可。需要说明的是,对接结构22与第二对接底板21可以但不限于一体成型结构。With reference to FIG. 1 , the second docking member 2 mainly includes a second docking base 21 and a docking structure 22 disposed on the second docking base 21 for the bolt to pass through. The power battery is provided with a corresponding matching with the docking structure 22 . The mounting structure 3 (see FIG. 3A), in the case where the mounting structure 3 extends into the docking structure 22, the mounting structure 3 can be secured to the mounting position by matingly connecting with the docking structure 22. Preferably, the docking structure 22 can be a nut with a threaded hole. The corresponding mounting structure 3 can be a bolt that is mated with the threaded hole. Of course, the form of the docking structure 22 and the mounting structure 3 are not unique, and those skilled in the art can adjust the form according to the specific application environment, as long as the form can satisfy the matching connection between the docking structure 22 and the mounting structure 3, and the power battery can be fixed. The conditions at the installation location are sufficient. It should be noted that the docking structure 22 and the second docking base 21 can be, but are not limited to, an integrally formed structure.
如图3A所示,为了提高安装结构3和对接结构22的配合连接成功率,还可以在对接结构22靠近第二对接底板21的一端设置导向孔23,并且该导向孔23的孔径沿螺栓的穿入方向成缩小趋势,如按图3A中方位所示的从下至上渐缩的环形导向孔等。这样一来,在安装结构3与对接结构22进行配合连接的过程中,只要安装结构3的顶端接触到环形导向孔,便可以顺利完成安装结构3与对接结构22的配合连接。显然,导向孔23的设置形式并非唯一,本领域技术人员在基于本发明原理的前提下,还可以对其作出调整,只要该形式能够满足沿对接结构22的孔远离第二对接底板21的方向为渐缩孔的条件即可。如导向孔23还可以是截面为梯形的导向孔或只在一个或两个方向上渐缩的楔形导向面等。As shown in FIG. 3A, in order to improve the success rate of the mating connection between the mounting structure 3 and the mating structure 22, a guiding hole 23 may be disposed at an end of the mating structure 22 adjacent to the second mating bottom plate 21, and the diameter of the guiding hole 23 is along the bolt. The penetration direction is a tendency to shrink, such as an annular guide hole that tapers from bottom to top as shown in the orientation in Fig. 3A. In this way, in the process of the mating connection between the mounting structure 3 and the docking structure 22, as long as the top end of the mounting structure 3 contacts the annular guiding hole, the mating connection of the mounting structure 3 and the docking structure 22 can be smoothly completed. Obviously, the arrangement of the guiding holes 23 is not unique. Those skilled in the art can also adjust the guiding holes 23 according to the principle of the present invention, as long as the form can satisfy the direction of the holes along the docking structure 22 away from the second docking floor 21. It is a condition for shrinking the hole. For example, the guide hole 23 may be a guide hole having a trapezoidal cross section or a wedge-shaped guide surface which is tapered only in one or two directions.
接下来参照图2和图3A,图2是本发明的动力电池的可调节安装组件的俯视图。如图2所示,第一对接件1主要包括第一对接底板11以及设有开口的容纳腔。其中第一对接底板11上开设有安装孔14,第一对接件1可以通过该安装孔14固定连接于电动汽车的车身4。在第
一对接件1通过安装孔14固定连接于电动汽车的车身4后,第二对接件2可以在容纳腔的设定范围内移动。如前所述,通过该移动可以使动力电池的安装结构3与第二对接件2的对接结构22配合连接。优选地,安装孔14可以为设置于第一对接底板11左右两侧的两个螺纹孔(按图2方位),第一对接底板11可以通过螺栓或螺钉等连接方式固定于电动汽车的车身4。当然,本领域技术人员可以理解的是,动力电池的安装结构3若想伸入第二对接件2的对接结构22中,第一对接底板11对应对接结构22的孔的位置需要开设有通孔。优选地,该通孔的直径大于环形导向孔23最下端的直径。Referring next to Figures 2 and 3A, Figure 2 is a top plan view of an adjustable mounting assembly for a power battery of the present invention. As shown in FIG. 2, the first docking member 1 mainly includes a first docking base 11 and a receiving cavity provided with an opening. A mounting hole 14 is defined in the first docking base 11 , and the first docking member 1 can be fixedly connected to the body 4 of the electric vehicle through the mounting hole 14 . In the first
After the pair of connectors 1 are fixedly coupled to the vehicle body 4 of the electric vehicle through the mounting holes 14, the second docking member 2 can be moved within a set range of the accommodating chamber. As described above, the mounting structure 3 of the power battery can be mated with the mating structure 22 of the second docking member 2 by this movement. Preferably, the mounting holes 14 may be two threaded holes (in the orientation of FIG. 2) disposed on the left and right sides of the first docking base plate 11. The first docking base plate 11 may be fixed to the body 4 of the electric vehicle by bolts or screws. . Of course, it can be understood by those skilled in the art that if the mounting structure 3 of the power battery is to be inserted into the docking structure 22 of the second docking member 2, the position of the first docking base 11 corresponding to the hole of the docking structure 22 needs to be opened. . Preferably, the diameter of the through hole is larger than the diameter of the lowermost end of the annular guide hole 23.
如图2和图3A所示,在一种优选的实施方式中,该容纳腔可以由如下特征围设形成:As shown in FIG. 2 and FIG. 3A, in a preferred embodiment, the receiving cavity can be formed by the following features:
第一对接底板11面对面的两侧延伸出一对翻边12,且一对翻边12在自由端相向延伸。第一对接底板11与相向延伸的一对翻边12围设形成该容纳腔,且一对翻边12的自由端分别设有凹进部,两个凹进部围成上述开口。其中,第二对接件2的第二对接底板21容纳于该容纳腔,并且第二对接底板21可以在容纳腔内移动。其中,第二对接件2的对接结构22伸出开口,并且对接结构22可以在开口内移动。A pair of flanges 12 extend from opposite sides of the first butt joint bottom plate 11, and a pair of flanges 12 extend toward the free end. The first docking base 11 and the pair of oppositely extending flanges 12 enclose the receiving cavity, and the free ends of the pair of flanges 12 are respectively provided with recesses, and the two recesses enclose the opening. The second docking base 21 of the second docking member 2 is received in the receiving cavity, and the second docking base 21 is movable in the receiving cavity. Wherein, the docking structure 22 of the second docking member 2 protrudes out of the opening, and the docking structure 22 can move within the opening.
按照图2所示方位,第一对接底板11可以为大致成长方形的底板,该长方形底板上下两侧分别按大致竖直向下和大致竖直向上的方向延伸出一对相向的翻边12,第一对接底板11、一对翻边12围设形成上述容纳腔,并且两个相向的翻边12的自由端(按图2方位,自由端分别为上翻边的下端和下翻边的上端)分别开设有大致成矩形的凹口,两个凹口围设形成一个完整的矩形开口。其中,第二对接底板21容纳于容纳腔中,对接结构22伸出矩形开口,并且矩形开口可以限制对接结构22在水平方向和竖直方向的移动。此外,翻边12在垂直于第一对接底板11的方向上的尺寸也可以大于第二对接底板21的厚度(参照图3A)。在这种情形下,第二对接件2沿轴向也可以在容纳腔内产生一定的位移量。According to the orientation shown in FIG. 2, the first docking bottom plate 11 may be a substantially rectangular bottom plate, and the upper and lower sides of the rectangular bottom plate respectively extend a pair of opposing flanges 12 in a substantially vertical downward direction and a substantially vertical upward direction. The first docking bottom plate 11 and the pair of flanges 12 enclose a receiving end, and the free ends of the two facing flanges 12 (in the orientation of FIG. 2, the free ends are respectively the upper end of the upper flange and the upper end of the lower flange) Each of the recesses is formed in a substantially rectangular shape, and the two recesses are surrounded to form a complete rectangular opening. Wherein, the second docking base 21 is received in the receiving cavity, the docking structure 22 extends out of the rectangular opening, and the rectangular opening can restrict the movement of the docking structure 22 in the horizontal direction and the vertical direction. Further, the dimension of the flange 12 in a direction perpendicular to the first butting base 11 may also be larger than the thickness of the second docking base 21 (refer to FIG. 3A). In this case, the second abutting member 2 can also generate a certain amount of displacement in the accommodating chamber in the axial direction.
本领域技术人员能够理解的是,虽然上述第一对接底板11大致为长方形,但这并非旨在限制本发明的范围,在不偏离本发明原理的基础上,可以对此做出调整,如正方形或圆形的第一对接底板11等。同样地,一对翻边12的设置位置及设置方式也并不唯一,仍按照图2方
位所示,一对翻边12也可以分别设置于第一对接底板11的左右两侧,或者分别设置于上下、以及左右两侧。也就是说,第一对接底板11的形状、翻边12的设置位置以及设置形状、设置数量都可以适当调整,只要其满足能够围设成大致呈环形的开口,并且该开口能防止第二对接件2脱出容纳腔的条件即可。It will be understood by those skilled in the art that although the first docking base 11 is substantially rectangular, this is not intended to limit the scope of the present invention, and may be adjusted, such as a square, without departing from the principles of the present invention. Or a circular first butt joint 11 and the like. Similarly, the setting position and setting mode of the pair of flanges 12 are not unique, and still follow the figure 2
As shown in the figure, the pair of flanges 12 may be respectively disposed on the left and right sides of the first butted bottom plate 11, or may be respectively disposed on the upper and lower sides and the left and right sides. That is, the shape of the first butted bottom plate 11, the position of the flange 12, and the shape and the number of the settings can be appropriately adjusted as long as it satisfies an opening which can be enclosed in a substantially annular shape, and the opening can prevent the second butt joint The condition that the piece 2 is taken out of the accommodating chamber can be.
下面结合图3A和图3B来阐述本发明的动力电池的可调节安装组件的工作原理。其中图3B是本发明的动力电池的可调节安装组件的一种优选实施方式的安装过程示意图二。如图3A和图3B所示,使用本发明的动力电池的可调节安装组件进行动力电池安装时,其安装过程可以是:The operation of the adjustable mounting assembly of the power battery of the present invention will now be described with reference to Figures 3A and 3B.

Then, the electric change trolley continues to lift the power battery, and during the process in which the power battery is continuously lifted, the mounting structure 3 on the power battery contacts the guide hole 23 of the screw hole of the mounting assembly. As the power battery is further lifted, the second docking member 2 is horizontally moved within the receiving cavity of the first docking member 1 by the substantially upward force exerted by the mounting structure 3 until the mounting structure 3 and the threaded hole are substantially the same Stop moving after the axis state.
